Addressing player performance

I have a player that continues to shoot us out of games and they only thing I can do is talk about how to modify his tendencies via "lets talk about your game" text.Is there a possibility that in the future we can talk about his overall performance in the text the player function. I think that just addressing the Playstyle is too neutral! I need to tell my players "hey you played pretty bad today" after 4-15 FG display to see how he responds, right now he has the talent but I cant see his mentality to improve because him saying I don't want to change my playstyle doesn't address the part of him actually playing bad in a game or streak of games. 47-155 this season in FG and 17-88 from 3 point land. I have asked him to change his game but he wont. The only thing I can do is bench him as his desire for play time is "expects starter minutes", but that doesn't really help fixing his performance. I'm stuck lol.
